Acknowledgement
We would like to thanks our supervisor Mr. Lam Wee Wah for his guidance and patience with us through our final year project. Mr. Lam has thought us a lot through this period of time. He has always been helpful to us. Moreover, he is willing to take his time to provide guidance to us, helping us in times of doubts and providing us with resources to our project. The feedback that he gave us and the resource provided by him has been useful for us. Mr. Lam is also always willing to check our progress and works and that allow us to keep track of our project flows
Blades Servers vs. Rack Servers
Blades Servers
A blade server is a server chassis housing multiple slim modular electronic circuit boards named server blades, each blade is an individual server in its own right. Blades are literally servers on cards, containing processors, memory, integrated network controllers, an optional Fiber Channel host bus adapter and other IO ports. Blade servers allow more processing power in lesser rack space, simplifying cabling and reducing power consumption
A rack server, which is also called a rack-mounted server, is known as a computer dedicated to use as a server and designed to be installed in a framework called a rack. The rack contains multiple mounting slots or bays, each designed to hold a hardware unit secured in place with screws. Rack servers have low-profile enclosures, in contrast to tower servers, which are built into upright, standalone cabinets.
A single rack may contain multiple servers stacked one above the other, consolidating network resources and minimizing required floor space. The rack server configuration also simplifies cabling issues among network components. In an equipment rack filled with servers, a special cooling system is required to prevent excessive heat buildup that would otherwise occur when many power-dissipating components are confined in a small space.

Blades Servers vs. Rack Servers
| Rack Mounted Server | Blades Server |
| Inflexible | Flexible |
| Lower Cost | Higher cost |
| Occupy more spaces | Save spaces |
| Higher power efficiency | Lower power efficiency |
| Number of expansion slots base on the size of rack mount | Limited number of expansion slots for storage or network needs |
| Support eight or more CPU sockets | Support up to four processor sockets |
Conclusion
With blades server, it goes green because it provides:- Energy saving
- Cost saving
- Environmental improvements
- More physical space
- A better working environment
